UNITED STATES PATENT OFFICE.

HEZEKIAH MORTON, OF THOMASVILLE, NORTH CAROLINA;

CHAIR-SEAT suPPoRf.

srncrrrcArrolv forming part of Letters Patent No. 655,506, dated August 7, 1966. Application filed June 1, 1900. Serial No. 18 700. (No model.)

To all whom it nutty concern:

Be it known that I, HEZEKIAH MORTON, a citizen of the United States, and a resident of Thomasville, in the county of Davidson and State of North Carolina, have invented a new and Improved Chair-Seat Support, of which the following is a full, clear, and exact de scription.

The object of the invention is to provide a new and improved chair-seat support which is simple and durable in construction and arranged to form a firm support for the seat to preventthe same from sagging and to relieve the chair-frame from undue strain byforming a brace for the chair and holding the posts of the chair firmly in position, thereby preventing the backs from coming out of the mortises, as the back posts cannot spread at their upper ends.

The invention consists of novel features and parts and combinations of the same, as will be fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure 1 is a side elevation of the improvement as applied. Fig. 2 is an inverted plan view of the same on the line 2 2 in Fig. 1; and Fig. 3 is an enlarged cross-section of one of the straps, the section being on the line 3 3 in Fig. 2.

The improved chair-seat support consists of two crossed straps A A alike in construction and extending directly under a chair-seat B, as is plainly illustrated in Fig. 1, so as to form a support for said seat and prevent the same from sagging. Each of the straps AA is formed of two parallel spaced pieces A A preferably made of flat metal and connected with each other at the ends by cross-pieces A fastened by rivets O to the spaced pieces A A''", as is plainly indicated in Figs. 2 and 3. The cross-pieces A form a passage for a bolt D, which extends obliquely through each leg E of the chair, the head D of said bolt D abutting against the outer portion of the leg and the nut D of the bolt screwing on the inner threaded end of the bolt to abut against the inner edges of the cross-pieces A, as is plainly shown in Fig. 2. It is understood that the nut D for each b olt extends between the two spaced pieces A A of each strap to prevent the nutfrom turning, the cross-pieces A forming an abutment for said nut.

Now when it is desired to tighten the straps it is only necessary for the operator to turn the heads D of the bolts from the left to the right to screw the bolt in the nut, which thus exerts an outward pressure against the cross- .pieces A and tightens the straps A A.

By the arrangement described a very flrni brace is formed for the frame of the chair, so that none of its parts are liable to be discon nected. It also prevents the seat-frame from breaking, and at the same time the arrange-' ment prevents the upper parts of the back from spreading and becoming disconnected, as is so frequently the case in chairs heretofore constructed. It is further evident that the sup port, being made of thin flat metal pieces, is not unsightly, can be readily attached to any chair, and greatly relieves the seat'of undue strain when the chair is used.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent 1. A chair-seat support, comprising crossed straps extended under the chair-seat to dia onally connect a front leg with a rear leg of the chair, each strap consisting of two spaced pieces connected at the ends, adjusting and supporting bolts extended from the legs through openings in said end connections, and nuts on the inner ends of said bolts, the

said nuts having abutment against said end connections and being prevented from turning by engaging with the members of the straps.

2. A chair-seat support, comprising crossed straps extending under, a chair-seat, to diagonally connect a front leg with a rear leg of a chair-frame, each strap consisting of two parallel spaced pieces of fiat metal, crosspieces for connecting the ends of the parallel spaced pieces with each other, said crosspieces also forminga passage for a bolt and an abutment for the nut of a bolt, and adjusttoo ing and supporting bolts extending through name to this specification in the presence of I the legs and through the passage formed by two subscribing Witnesses. the cross-pieces, the nut of the bolt extendin between the parallel spaced pieces and abut HEZEKIAH MORTON 5 ting againstthe inner edges of the cross-pieces, Witnesses:

as set forth. G. E. GODWIN,

In testimony whereof I have signed my J. A. ELLIOTT. U
